Place all ingredients in a large mixing bowl. Beat at
low speed until ingredients are combined. Then, beat
at high speed until stiff glossy peaks form when
beaters are lifted, about 5 to 7 minutes. Icing is
best used right away, but can be covered with plastic
wrap or a damp cloth and kept at room temperature for
2 to 3 hours.
